Comment= # 1 on bug 98874<= /a> from Michel D=C3=A4nzer 
Sounds like a GPU hang, which is most likely caused by Mesa or=
 LLVM. With the
environment variable GALLIUM_DDEBUG=3D"pipelined 2000" set for th=
e compositor or
Xorg process, the radeonsi driver might detect the hang and dump some
information about it in a file in ~/ddebug_dumps/ . Please attach that file
here.

The failure to recover cleanly from the problem is a kernel issue. You can =
try
setting amdgpu.lockup_timeout=3D2000 to make the amdgpu driver detect the h=
ang
and try to reset the GPU, but it doesn't work reliably in general yet.
